Straight pressure plates create an eccentric tension force as well as an osteosynthesis with angle pressure plates. Both kinds of plate incline to gape the osteosynthesis and/or fracture gap. Therefore an overbending or additional angle allowance is necessary. In our biomechanical investigations we showed that at average bone stability, an overbending of the angle respectively an additional angle allowance of 3 degrees is most favourable. Uniform distribution of power transmission can be achieved at the entire osteotomie level using large and small angle plates with appropriate plate thickness and plate tension force. Sufficient stability in mobilisation is guaranteed without additional cast fixation.
直形加压钢板会产生偏心拉力，同时与角形加压钢板一样具有骨接合作用。这两种钢板都倾向于使骨接合和/或骨折间隙增宽。因此，需要进行过度弯曲或额外的角度预留。在我们的生物力学研究中表明，在平均骨稳定性情况下，角度过度弯曲或额外预留3度角是最有利的。使用具有合适钢板厚度和钢板张力的大角度和小角度钢板，可在整个截骨水平实现动力传递的均匀分布。无需额外的石膏固定就能确保在活动时有足够的稳定性。
